How Illinois fits in
Illinois taxes individual income at a flat 4.95 percent for 2026, and the calculator applies that rate with no state standard deduction. Illinois does allow an exemption: the Illinois Comptroller Payroll Bulletin 1-26, citing the Department of Revenue booklet IL-700-T, gives $2,925 per exemption for 2026, up from $2,850. One exemption lowers yearly Illinois tax by about $145 (2,925 times 4.95 percent). This estimate does not claim any exemption, so your actual Illinois tax may be slightly lower. Both the rate and the exemption are stated in the Comptroller bulletin 1-26 (PDF).
The federal side works the same in every state. If you want to see how the brackets and the standard deduction are applied, read our guide to the 2026 tax brackets, or how FICA is calculated on a biweekly paycheck.
What this estimate leaves out
The figures above assume a single filer taking the 2026 standard deduction, with no dependents and no pre-tax contributions. Contributing to a 401(k) lowers your taxable income, and you can test that in the calculator. The estimate also leaves out the Illinois exemption, itemized deductions and tax credits.
